ABSTRACT:
A standard cell arrangement can be produced by automatically determining a distance between at least two standard cells in at least one standard cell row. The method also automatically determines whether at least one of the determined distances is less than a predetermined minimum distance. If the distance is less than the minimum distance in at least one case, the width of at least one standard cell in the standard cell row in a virtual layout of standard cells is broadened in a predetermined manner. The broadened standard cell is automatically placed in the virtual layout with other standard cells. The placement of the broadened standard cell in the virtual layout is transferred to the real layout of the standard cells. In this manner, the standard cells are provided with the originally intended width again, in order to create greater distances between the standard cells in the real layout.
